The JR-1000 series is the easiest to use temperature data logger available. With its precision calibrated internal
temperature sensor, simply place the logger in the field and leave it to record. Once the desired information has
been recorded, plug the logger into the serial port of your computer and begin downloading and viewing the logged
data with ACR’s TrendReader® Express software.
